'YARN-GATGHER non srIniiING-MAcnnvEs.

zen of the United States,"res1'ding at Concord Junction n the county of Middlesex and State of Massachusetts, "have invented" certain new and useful Improvements n Yarn-Catchers for Spinning-Machines, of which the following isafull, clear, concise, and exact description.

My present invention has for its principal for holding the yarn in operative relation to the spindle, whereby the excessive waste of yarn which during the removal of full and the application of empty bobbins to the spindle is avoided.

Another object isto provide a device of this character which may beemployed upon spinning mules of the type now in general use at a comparatively small cost, without the necessity-of making extensive alterations in the construction of said mules. V

With these and other objects in view, my invention consists of a support mounted, frictionally or otherwise, on the spindle, below the bobbin, at one side of which support ispivotally mounted an angular member, is adapted to be moved into engagement with the spindle above or below the support, and being held in either of its two positions by a spring. A movable ringor collarhaving a reciprocating movement parallel to the axis of thespindle ennary form, a portion only of said mule being the arms of the angular member to move said arms into position-to grasp or release the yarn to be wound on the bobbins. p

two of these spindles are shown in Fi 2 but 1t is to be understood that the nuriiloei of spindles employed is onlylimit'ed'by the capacity of the machine. *These spindles are supplled with pulleys or whirls 12, by means of which they are rotated A friction collar 13, for holding thebobbins 14;, is

mounted on the spindle 11 in any convenient manner. 1

Attached to the spindle 11 and rotatable therewith, is a sleeve 15. This sleeveis located between the whirl 12 and the friction collar 13 and carries at its upper 'end a support 16, shown in plan in Fig. 8. This support 16 may be separate from the sleeve 15 and fastened thereto in any convenient manner, or it may be made integral with the sleeve 15, as by casting. An angular member, comprising two arms 17 and 18, connected to a central portion 19, is pivotally mounted at one end of the part '16,. At the other end of the part 16 are two arms or proyectlons 20 and21, groovedon their ends to receive a coil spring 22, each end of which sprmgis attached to the ends of apin 23 extending through andfastened to the part 19. The face of the arm 17 is grooved to fit the spindle 11, as clearly shown in Fig. 3. to more firmly grasp the yarn. The face" of the arm 18 may be grooved also, but it is not essential.

In the position of the angular member shown n F1g. 1, the arm 17 isin engagement with the spindle, and gripping the Mounted on the rail 10 are'bearing blocks 25 and 26', in which is rotatablyomounted the shaft 27. These bearing blocks [are attached to therail 10 by bolts 28, or'in any other suitable manner. Attached to the shaft 27 by set screws 29 is a plate 30 providedwith perforations 31. On the end of the shaft 27 is fastenedan operating lever placed onthe spindle.

32 by means of which the outer end of the plate is moved upward ordownward with respect'to the spindle 11, and being held in its extreme positions by the catch 33 engaging with one or the other of the notches 34 in a quadrant 35 fastened to the rail 10 by the bolts 36. The plate 30 in its movement engages one or-the other of the arms 17 and 18, movingthe same upwardly or downwardly against the tension of the spring 22, until the pin 23 passes the pivot point of the angular member, when the spring 22 will force said arm into engagement with the spindle llor sleeve 15, respectively.

In the operation of the device,th e arm 18 isfusually in engagement with the sleeve 15, the plate 30 being in its lowermost po sition, as indicated bythe dotted .lines in Fig. 1. An empty bobbin .14 is placed on the spindle 11 and the operation of wind- 7 ing the yarn 24: on the bobbin takes place in the usual manner, the taller wire 36 being moved upward and downward to guide the yarn onto the bobbin. When the bobbin is full, the taller wire is depressed to guide the yarn 2%, downward onto the spindle 11 a and below the collar 13. After one or two turnsof the yarn are on the spindle, the le- 7 ver 32 is operated to move the arm 17 upward into engagement with the spindle 11 to firmly hold the yarn 2%.. The full bobbin may now be dotted and an empty bobbin In the dofling'the yarn breaks close to the spindle, but the arml7, holding the turns of yarn against thespindle, prevents the yarn from flying loose when the full bobbin is dotted.- When i the empty bobbin is in place, the taller wire 36 is again raised to guidethe yarn onto the bobbin. At anytime before the bobbin is full, the plate 30 may be lowered to free the loose end of the yarn from the spindle, in preparation to repeat the operation above described' It will be obvious, from the above description, that a substantial saving of yarn is effected over the methods 110w employed,

and that but one or two turns of the yarn around the spindle are necessary for the dofiing operation. These one or two turns amount at most to less than two inches. This seeming waste is all carried by the next bobbin used, so that, in reality, no Waste takes place. In the methods at present employed, not only is there a possible waste of two inches, but the dozen'or fir" 7 teen turns of yarn around the spindle and which must be cut from the spindle by" a knife or other like implement, is an absolute waste, and this waste is avoided by the 7 use of my invention.

While I have described the preferred embodiment of my invention, it will be understood that minor changes in the 'ldetails of construction and arrangement of parts may be made within the scope of the appended claims without departing from the spirit of the invention. 1 v

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

1. A- yarn catcherfor spinning machines,

comprising, a spindle, a support mounted thereon and rotatable therewith, a holding member, pivotally mounted on said support, and adapted tov hold the yarn extending from the mule to the bobbin, against the spindle.

2; A yarn catcher for spinning machines comprising, a spindle, a support mounted \thereon and rotatable therewith, a holding member pivotally mounted on said sup ort' and including av pair of radially exten ng arms, means for selectively engaging said armsto rock the holding member into or out of position to hold the yarn extending from the mule to the bobbin, against the spindle.
